3 Claims.

The invention has relation to listing adding machines, and more particularly to means for automatically ejecting a statement sheet from such a machine as part of a special program of operation.

The invention consists in the novel construction and combination of parts as set forth in the appended claims.

Thepresent disclosure shows the invention apwith a platen carriage, as disclosed in U. S. Patent No. 1,945,026, issued on January 30.1934 to the present inventor and with tabulating mechanism disclosed in U. S. Patent No. 1,946,572, issued February 13, 1934, also to the present inventor.

In the accompanying drawings, illustrating the invention:

Figs. 11 and 12 are detail views of the clutch operating mechanism. i

In these drawings the numeral 500 (Figs. 1-5) designates the cylindrical platen, mounted in a transversely shiftable carriage which is provided also with means for holding a statement sheet in 7 position opposite the printing devices in the base of the machine.

During the printing operation, the statement sheet is held against the platen by idler rolls 53L mounted upon plates 532 which are movable to bring the rolls 53! out of contact with the platen 500 when the statement sheet is to be ejected out hrough the platen the carriage being plied to a Gardner calculating machine provided 1936, Serial No. 86,072

of the machine and a new sheet inserted. In this movement of plate 532 to open position a pair of feed rolls 501, 508, normally held apart from each other (Fig. 4), are brought into contact (Fig. 5), whereupon rotation of roll will feed the statement sheet, between said roll and roll 508, out of or into the machine.

The paper rests upon guides 50B carried in a frame which is adjustable relatively to the platen carriage proper, the two frames being connected by links 526, best seen in Fig. 3. Means are provided whereby movement of the paper guide frame upon the links 526 will adjust the rolls 501, 508 and 53! in the manner above mentioned, this means comprising a toggle link 52'! between the two frames, which toggle will be in the bowed position shown in Fig. 2 when the carriage is closedv (that is to say when the rolls 53ll are against platen 500 and the rolls 501, 508 are separated). Straightening of toggle 521 into the position shown in Fig. 3 will move the plate 532 into open position by means of a link 533 connecting said plate with the forward link 525. This forward link 526 is also provided with a projection 529 which in the movement of the parts to open position will engage a spring retracted plate 530 upon which the rolls 508 are mounted, and will thereby force the rolls 508 into contact with the rolls 507, the latter being mounted upon a shaft 500 journaled in the paper guide frame.

The carriage is opened automatically, in connection with means for automatically ejecting the statement sheet, and may be closed by the operator through manipulation of a thumb lug formed in one of the elements of the toggle 521.

The carriage is automatically opened by operation of rods 538, pivotally connected to the toggles 521! at opposite sides of the machine, a bail 560 being pivotally connected to the lower ends of the rods 538 and normally held, by a spring 5M in position against the rear face of or above a bail 562, pivotally mounted in the base of the machine at 563, as seen more clearly in Fig. 6. Spring 5613 has a toggle effect upon bail 560, so that, as the carriage comes to closed position bail 550 will swing from a rearward position toward bail 552.

When the machine is operated in accordance with the controls illustrated herein, the platen carriage ismoved back and forth between two adjacent tabulatingpositions, and movement of the carriage from one tabulated position to the other bringing one or the other of two opposed cams 555 (Fig.- 1) into contact with a roller 565, fixed upon the bail 562, forcing the bail into its lower position, bail 560 being thereupon moved by spring 56I to position above bail 562. Bail 562 is held in either of its two positions of adjustment by means of a toggle spring 566, one arm of said spring being fixed to the frame of the machine.

The platen carriage is moved into its left-hand position (depressing the bail 562) by means of a tape 9, attached at one end to the carriage and at the other end to a spring drum 8 (Fig; '1). This movement of the carriage will occur upon the movement of a stop lever 1 (Fig. 8) to active position, this stop lever being mounted in the frame of the machine and having a lug 6 adapted to engage in notches of a tabulator bar I mounted in the carriage. Stop lever 1 is released near the end of a printing cycle of the machine by means of a pawl I84 having pin and slot connection I85 with the frame of the machine and being adapted to be lifted from the position illustrated in Fig. 8, to a position overlying lug 6 of stop lever 1, by means of a lever I19 having a lug I80 engageable beneath the shoulder of a dog I82 pivoted upon pawl I84, lever I19 being operated by lever I1-1 (Fig. 6), I61, I'll, shaft I64, lever 321, link I62 and arm 3I6, from the oscillating driving shaft 30I of the machine. In engaging over lug 6, pawl I84 moves dog I62 away from lug I80, whereupon a spring I81 will pull pawl I84 and stop arm 1 downwardly, releasing the carriage for movement to the left under the influence of spring drum 8.

The printing operation of the machine will also act to raise the bail 562, and'thereby the bail 560 and rods 538, to open the carriage, this movement of bail 562 being effected by means of a roller 561 (Fig. 9) fixed upon the driving link I08 between arm 3I6 and the driven member I of the main clutch, roller561 for this purpose contacting the end of a lever 568, having a rearward extension 569 engaging a pin 510 fixed in a forwardly extendingarm ofbail 562.

The printing operation being completed and the carriage opened, the paper will be ejected and the carriage returned to the right as follows:

A tape 24I (Fig. 1) is fastened at one end to a drum 269, fast upon the shaft 268 which has gearing connection 5I0, 5 with the shaft 509 upon which the feed rolls 501 are mounted. The other end of this tape is attached to a drum 235 (Fig. 10) having spring connection with a hub 231, this hub having'in turn friction clutch connection 229, 234 with a motor driven shaft 23I.

Feeding of a statement sheet into the machine will wind-tape 24I about the drum 269, and upon engagement of the friction clutch, tape 24I will first rotate the drum 269 reversely, ejecting the paper by means of the feed rolls 501, 508, and after the tape is completely unwound from drum 269, continued operation through the clutch will return the carriage to the right, until the clutch is disengaged, whereupon spring drum 8 will engage the notch of tabulator bar I with the stop lug 6, to locate the carriage in its right-hand printing position.

The friction clutch is controlled as follows:

An arm I98 (Fig. 6), fixed upon the shaft I99 in the base of the machine, is provided with a roller I91 lying in the path of movement of a cam shoe I95 mounted in the platen carriage. Upon movement of the carriage into the lefthand position shoe I95 will contact roller I91 and rock arm I98 and shaft I99. Fixed upon fixed in the framing of the 'clutch by operation of the well known ,efi'ected as the carriage is hand position.

' .shaft I99 is a forward arm 2I8, having yieldable connection 2I9 with a link 220, the other end of link 220 is pivoted to a latch 222, carried upon a plate 223. Upon rocking of shaft I99 latch 222 will be pressed against a pin in the motor driven lever 321, movement of said lever in the operation of the machine causing latch 222 to dropbehind the pin and to be operated thereby in the return movement of the parts. This will effect rocking of the plate 223, which plate has a yieldable link connection 226 with an angularly bent arm of plate 221 (Figs. 6, 10, 11 and 12). Plate 221 is provided with lugs 228 lying between two plates 229 of the clutch. Movement of plate 223, by its connection with the right angle arm of plate 221 will rock" the latter plate on an axis running through the lugs 228,

whereby said lugs will act to force the plates 229 oppositely toward plates 235 of the driven element of the clutch. Suitable anti-friction devices are interposed between the plates 229 and 235.

Upon movementof the platen carriage into its right-hand position, roller I91 will encounter a cam shoe I96, mounted in the carriage, and

projecting oppositely to the cam shoe I95, whereby arm I98 and shaft I99 will be rocked in the opposite direction, retracting latch 222 from the pin in arm 321 and thereby releasing the clutch.

Means are provided for opening the carriage and ejectirfg the statement sheet with the carriage located in its right hand position, this means comprising a roller 51I (Fig. 6) fixed upon an arm of the bail 562, and adapted to contact with a shoulder 512 of an arm 513, pivotally connected to the arm 2I8. Upon lifting of bail 562 from the position illustrated in Fig. 6 roller 51 I, by engagement of shoulder 512 will push arm 513 forwardly, rocking arm 2I6, to engage the clutch as hereinbefore described. In this movement of ball 56} an edge 514 of arm 513 will engage a pin machine, preventing further movement of arm 513 with ball 562, so

that roller 51I will ride over the angle of shoulder- 512 and engage the upper surface of arm 513. Roller 51I will be brought again into position opposite shoulder 512 when bail 562 and arm I98 are moved into the positions therein illustrated, as set forth in the appended description of operation.

The printing operation of the machine may be effected by operation of the add key. II4, acting to release a spring operated lever I06 from latch II2, thereby effecting the'release of clutch pawl I03, pivoted upon the driven clutch member I05 from engagement with lever I06, and allowing the pawl to drop into engagement with the teeth I04 of the driving clutch member. Alternatively, lever I06 may be released to effect the total or sub-total key means, and automatic operation of the total mechanism may be effected by pulling down the total key, as described in U. S. Patent No. 1,994,211, issued March 12, 1935 to the present inventor. In the present case the arm 206 (Figs. 1, 3 and 6) which effect the depression of the total key is operated by means of a cam 515, mounted upon the carriage, contacting with a roller 516, fixed on the arm 206, this contact'being moved into its left The lever 568 which effects the setting of the parts for the opening of the carriage and the ejection of the statement sheet upon the succeeding operation of the machine, may be provided with a forward key extension whereby the machine may be set to perform these operations whenever desired by the operator. This is principally useful when other programs of operation, not. specifically herein described, are being used. The setting of parts, whereby the cams I5, I96, etc. are moved into inoperative position and replaced by other control devices is fully described in the Patent 1,946,572, hereinbefore referred to.

Operation,

While the-invention may be useful in any one of a number of different applications, it is illustrated herein in connection with a program operation which is used in bank statement and other work, in preparing the statements for transmission to the depositors and in preparing new statement sheets upon which future entries are to be made. These statement sheets are customarily made in two detachable parts; a left-hand part which issent to the depositor and a right-hand part which is retained by the bank. The two tabular positions of the carriage hereinbefore referred to are designed to provide for printing upon the depositors'portion and the bank portion of the statement respectively. On the depositors portion the new balance is to be printed, this balance being copied from the final balance appearing upon the banks portion of the statement. Thereafter, this new balance is to be printed as an old balance upon both portions of a new statement sheet.

With the platen carriage of the machine located in its right-handposition; with the carriage open and with the control-mechanism in the position illustrated in Fig. 6, the operator inserts the old statement sheet into the machine and closes the carriage. The new balance is then set up on the keyboard of the machine and printed upon depression of the adding key 4, this serving also to register the amount of this new balance in an accumulator of the machine, in well known man- During this printing operation roller 56! of link I68 will contact with lever 568 and will thereby raise bail 562 to open the carriage, This raising of bail 562 will also bring roller 5' against the shoulder of am 513, to rock arm'2l8 and engage the friction clutch 229, 234. Engagement of the friction clutch will act to wind tape 2 on drum 235, to eject the statement sheet and to move the carriage slightly to the right, bringing roller I91 onto cam shoe I96 and thereby reversely rocking arm 2I8 to disengage the clutch. In this operation bail 562 remains in raised position, and roller 5H engages the upper surface of arm 513.

The operator now inserts a new statement sheet into the machine, closes the carriage and depresses the well known sub-total'key, whereby the balance which has been registered-in the" I brings roller l9'l against cam shoe I95 and roller 565 against cam 564, whereby the controls are set into position for opening the carriage, ejecting the new statement sheet and returning the carriage to the right, these operations following the printing of the total.

In moving back to the right, roller 565 will encounter cam 566 setting the controls in the position illustrated in Fig. 6, ready for the next series of operations.
